BUBBER-SOLED FOOTWEAR.

` QApplication mea April 14, 1927, serial No.

My invention relates to improvements in rubber soled footwear with more particular reference to shoes having crepe outer soles and the object of the invention is to improve the appearance of these shoes by obscuring the rather unsightly lateral edge of the outsole; a further object is to improve the durability of these shoes by providing a protective facing for the latera edge of l0 the outer sole whereby the tendency of this sole to break away at the edge and also to spread at the edge is prevented.

Other objects will appear in the course of the following specification.

My invention consists of rubber soled footwear, constructed as hereinafter more particularly described and illustrated in the accompanying drawings in which:-

Fig. 1 is a longitudinal section of the lower portion of a rubber soled shoe constructed in accordance with my invention.

Fig. 2 is a detached fragmentary longitudinal section of the toe portion showing the first step in the course of manufacture.

Fig. 3 is a transverse section through a middle sole used in my shoe showing a welt strip secured to the upper face thereof, the section being taken at the central portion of the length of the middle sole.

Fig. 4 is a fragmentary longitudinal section of. the middle sole and welt strip shown in Fig.A 3, showing the relative position ofA the welt stri at the heel and toe, where the gathering o the fullness at the turn causes the runnerv strip to stand upwardly from the middle sole.

Fig. 45 is a section taken similarly to Fig. 2 but shows the next step in the manufacture, in which the middle sole is attached to the upperand insole.

Fig. 6 is a section taken similarly to Figls. 2 and 5-showing the next step in which t e oulter sole has been secured to themiddle so e.

Fig. 7 is a section taken similarly to Figs. 2 and 5 and 6 showing the iinal step in which the runner strip has been downturned anld secured to the lateral edge of the outerso e.

In the drawings, like characters of reference indicate corresponding parts in the va' rious views.

In constructing a. shoe in accordance to my inventionthe upper 1 is first secured to 188,776, and in Canada February 18, 1927.

the insole 2 by lasting in the ordinary way and. is secured thereto. by the usual stitching 3. This step is illustrated in Fig. 2.

A Welt strip 4 of flexible leather is then secured to middle sole 5. 1 `f This welt stri is made from astraight sided strip of exible leather of uniform width throughout and is secured .to the upper face of the middle sole-5 by a row of stitching 6.

The strip 4 extends entirely about the middley sole 5 and the fullness caused by the turn at the toe and heelis taken up in the seam at these points, so that over the central part of the length of the middle sole 5 the strip lies flat as shown in Fig. 3, while at the toe and heel it stands upwardly from themiddle sole as shown in Fig. 4.

In the neXt step the middle sole 5 with the welt strip4 attached thereto is attached to the upper and inner sole and may. be secured thereto in any suitable manner, as by the ordinary McKay stitching 7.

Fig. 5 illustrates the position of the parts at the toe'of the boot at the end of this step.

-In the next step the rubber outer sole `8 is secured to the middle sole 5 in any suitable manner, as for instance by cementing. Fig.

6 illustrates the position vof the parts 'at the I toe at the completion of this step.

The outer face of the Welt strip 4 and the lateral .edges of the middle sole 5 and outer sole 8 are then coated with cementing solution and the welt strip 4 is downturned over the edge of the middle sole and outer sole and is firmly cemented thereto.

The position of the parts at the toe after the completion of this step is shown in Figs. 1 and 7.

By the manner in which the welt strip 4 is secured to the middle sole 5 so that the fullness at the turn of the toe and heel is taken up in the seam, when the runner strip is downturned over the middle sole and outer sole as described in the last step, this strip lies fiat without crease against the Llateral edge of the outer sole.

An examination of Figs. 1 and 7 willV show that the runner strip 4 forms a protectve facing about the lateral edge of the rubber outer sole 8, which facing entirely covers this lateral edge.

My construction is of particular value in the case of shoes havingthe outer `sole of 'crepe rubber since the rather unsightly lateral edge of thejsole is completely hidden by the protective facing.

Further this protective facing prevents the lateral spreading of the sole and also it prevents the breaking away of the sole at the lower edge.

In the form illustrated, is shown an insole 9 havin a sponge rubber heel 10 covered with soc lining 11. This heel is shaped at 12 to conform to the arch of the foot.

From the foregoing it will be apparent that I have devised an improved construction for rubber soled footwear whereby the objects of my invention have been attained.

Various modifications may be made in my invention without departing from the spirit thereof or the scope of the claims and therefore the exact forms shown are to be taken as illustrative only and not in a limiting sense and I desire that only such limitations shall be placed thereon as are imposed by the .prior art or are specifically set forth in the appended claims.

What I claim as my invention is:

1. In a shoe of the character described the combination of a middle sole, a Welt strip attached to the middle sole, an insole and stitching passing through the insole, upper,

welt strip and middle sole, and a rubber sole attached to the middle sole and Welt strip.

8. The method of making a shoe comprising attaching a welt strip to the middlesole, stitching an insole and an upper to the middle sole and attaching an outer sole to the middle sole and Welt strip. Y

4. The method of making a shoe comprising attaching a welt strip to the middle sole, stitching an insole and an upper to the middle sole and cementng an outer sole to' the middle sole and Welt strip.

5. The method of making a shoecomprising stitching a welt stri to a middle sole, stitching the upper and insole to the middle sole through the Welt strip and cementing an outer sole to the inner sole and welt strip.
